3 weeks!!!!!!!

My "baby" is going to be starting preschool in 3 short weeks. Believe me, there are times when I'd like to enroll him in boarding school full-time, but in reality I'm not ready for my little man to be away from me 5 days a week. Yes, he did "preschool" last year, but there is a big difference between a 2-day a week program for 2hrs/day and a 5-day a week program for 3hrs/day. My "sugar plum" is growing up, and I'm not sure I'm ready.
